Poppycock, Piers! That was dirty ‘Talent’ pool!

“Prince Poppycock,” one of the top showmen this season on “America’s Got Talent” performed his heart out for the final time tonight.

Yet, just because judge Piers Morgan thought he was too “serious” – not outlandish enough, in his opinion — he rudely buzzed him in the middle. Not because the prince missed a beat or didn’t sing well — because he didn’t do the kind of over-the-top extravaganza Morgan wanted.

I can’t remember a judge hitting the buzzer during the finals before. They’ve given criticism, yes, but the obnoxious buzzer should be reserved for screw-ups.

He dissed Poppycock again, in fact, after Michael Grimm’s soulful performance of “When a Man Loves a Woman.” Yes, Grimm was great, but Morgan didn’t have to put down “the previous performer” – as he dismissively referred to the prince – to compliment Grimm.

Morgan also nit-picked the final show presented by illusionists extraordinaire, Fighting Gravity. He pointed out a mistake and seemed to take the wind out of the young guys’ long-rehearsed sails.

The judge, in fact, seemed only to have eyes and ears for a 10-year-old: opera singer Jackie Evancho, who, yes, sang beautifully as usual. But a Las Vegas act? C’mon!

All four acts that made it to the finals were deserving of applause – and should have been shown equal respect.

Fellow judge Sharon Osbourne was right on the money when she snapped at Piers for being so egotistical and insensitive, saying America should be left to decide who wins the whole thing – including $1 million — Wednesday night, not Morgan.

Let’s just hope his subjective twaddle doesn’t get in the way of votes for an act that truly does belong in Vegas.
